Hello Vyd,

Truth alone is not sufficient as a criterion of knowledge. Firstly, if it is not accompanied by belief, then the knowledge of that truth is not creditable to agent. Secondly, the search for truth itself is a tricky one as people could disagree as to what the truth is, or certain 'truths' may turn out to be false over time (the belief that earth is flat; that earth is the centre of the universe, and so on).

When we are talking about knowledge, there is an agent involved. The beliefs of the agent, and the justification that the agent has for holding those beliefs. Whereas when we talk about truth. there is no agent involved. What is true is true regardless of the agent or their beliefs/justifications.

I would suggest that you read about Gettier cases. They further clarify how the JTB (justified true belief) definition of knowledge is inadequate.
